8 Claims (01. 15--191) This invention relates to brushes, and moreparticularly to means for fastening the component parts thereoftogether.

An object of the invention i to provide a brush of the paint brushVariety having novel means for fastening the handle and ferrule thereoftogether. I 1

Another object of the invention is to provide a paint brush havingfastening means on the ferrule adapted to. be secured in complementaryreceiving means on the brush handle.

A further object of the invention is to provide Other objects andadvantages of the invention will be apparent form the followingdescription taken in conjunction with the drawing forming.

part of this specification and in which:

Figure 1 is a vertical sectional view of a completely assembled opencenter type brush embodying the novel brush and ferrule fastening meansof the invention;

Figure 2 is a view in perspective of the ferrule alone; I l

Figure 3 is a view in perspective of the brush handle alone; and

Figure-4 is a Vertical sectional view of a completely assembled closedcenter type brush embodying the ferrule and handle fastening means ofthe invention.

Referring to the drawings for more specific details of the invention,Figure 1 illustrates a completely assembled .paint brush having a.

handle II), a ferrule I2, bristles I4, a cement composition I6impregnating the butt ends of the bristles I4 and adapted to secure thebristles to the ferrule I2 and to a wedged plug I8 driven between therows of bristles I4 to provide therebetween a space 20.

This invention is no concerned with the manher of securing the bristlesto the ferrule IE or the spacing of said bristles by the plug I8, themanner of so doing being conventional and well known in the art, but,rather, to the manner in which the brush handle I is secured to theferrule I2.

The handle I 0, as shown in Figure 3, comprises a gripping portion 22which may be flat or beavertailed in shape and a head portion 24 havingoppositely disposed grooves 26 extending the length of the sidesthereof.

The ferrule, more particularly shown in Figure straight sides 30,rounded, ends 32, and a shoulder encompassing an elongated slot 36centrally arranged with respect to the ferrule. A pair of spacedvertical plates 38, parallel to each other and arranged at the sides ofthe slot 36, have at their extreme ends inwardly turned flange portions40.

The head portion 24 of the handle I0 is connected to the ferrule I2 byan endwise insertion, or longitudinal sliding of said portion betweenthe unconnected ends of the vertical plates 38 so that the flanges 4B ofsaid plates are received within the grooves 26 of the handle. The handleand ferrule are thus secured together to prevent any wobbling actionbetween said members, and the prevention of any relative longitudinalmovement between the handle and ferrule is prevented by thepassing oftacks or nails through plate members 38 into the head of the handle.

The insertion of the impregnated butt ends of the bristles I4 into theferrule I2 and the wedging of plug I8 between the rows of bristles I4may either precede or follow the fastening of the handle to the ferrule,and after said insertion the sides 30 of the ferrule I2 are preferablypressed inwardly, as shown in Figure l, to more firmly retain thebristles within the ferrule.

The ferrule I2 is preferably made of a light metal, such as aluminum, bya die casting process to impart suflicient strength to the plates 38 Iof the ferrule so as to prevent any bending of said plates with respectto the cut portion 28 of the ferrule during normal use of the brush.

A modificationof the disposition of the bristles I4 of the brush toachieve what is known. as a solid center brush is indicated in Figure 4wherein two plugs I8 are used in combination with the side walls 30 ofthe ferrule I2 to separate the butt ends of three rows of bristles. Inthis modification of the completely assembled paint brush, the sides 30of the cut portion 28 of the ferrule are inclined inwardly to a slightlygreater extent than in the hollow center brush of Figure 1 to impart theproper lines and stiffness to the bristles.

While the preferred embodiment of the invention has been shown anddescribed, it is understood that modifications in this embodiment may bemade within the spirit of the invention and the scope of the appendedclaims.

What I claim as new and desire to secure by Letters Patent is:

1. In combination, a brush ferrule comprising an elongated cup havingsides and a base, a pair
